HEEL-NAIL;

SPEGIFICATION forming part of Letters Patent No. 424,430, dated March25, 1890. Application filed .l'uly 25.1889. Serial No. 318,602. (Nomodel.)

To all whom it may concern:

Be it known that I, HENRY R. PACKARD, of Taunton, in the county ofBristol and State of Massachusetts, have invented a new and usefulImprovement in Heel-Nails, of which the following, taken in connectionwith the accompanying drawings, is a specification.

This invention relates to the class of nails especially adapted for usein shoe-heels where the outer lift is applied afterthe body of the heelhas been nailed together, such outer lift being spanked on and caused toadhere to the projecting heads of the nails without being penetrated bytheir bodies.

The lVebster patent, No. 394,802, dated December 18, 1888, represents aheel-nail having a split or V-shaped head, the two oblique wings ofwhich meet at an acute angle and become merged in the body of the nail.Such nail lacks two features peculiar to minenamely, a defined shoulderor stop at the under surface of the head to prevent driving in too farand a broad seat or space between the upturned wings to receive enoughof the leather of the outer lift to prevent the nail from working downand out when in use.

My improved nail is preferably cut from a metal plate and made with abody tapering half its length to a clinching-point. The wings of thehead taper as they recede from the body, and may have barbs or hooks atthe tips.

In the drawings, Figures 1 and 2 are enlarged side and edge elevationsof my improved nail, and Figs. ll and 5 like views of the same barbed onits wings. Fig. 3 is a section through a heel, showing the nail securingthe outer lift by its wings.

A is the body of the nail, and B B the upturned wings of the head.

C is a shoulder or stop at the under side of the head where it joins thebody, and D is a broad seat on the upper surface of the head Such seatis either fiat or slightly curved to separate the wings widely, and isto be distinguished from the acute angle of divergence of the wings ofthe V-shaped wire n ail already referred to. The head of my nail may incontrast be called U-shaped7 with the wings somewhat inclined outwardlyand with a defined shoulder below them.

The barbs E (shown in Figs. 4 and 5) aid in securing the outer lift Fwhen it is applied over the nail-heads, their tips penetrating` amongthe fibcrs and the barbs resisting withdrawal. The shoulder O preventsthe head from being forccd into the heel-body G, while the seat Dreceives enough of the stock of the outer lift to keep the nail fromworking out.

I disclaim and distinguish from my invention the minute tack ortemporary fastening for outsoles to insoles shown in the King patent,No. 392,677, dated November 13, 1888, and consisting of a conical prongtoo short to pass through the ordinary insole of a shoe, and twodivergent curved prongs extending outwardly from the base of suchconical prong to enter the inner surface layer of the outer sole andhold it in place on the inner sole until the two can be united by theusual sewing, pegging, or nailing. My nail, on the contrary, is thepermanent and only fastening which secures the outer lift of the heel tothe body thereof and to the sole and insole of the boot or shoe. To thisend it has, in addition to the peculiar head and shoulder described, anelongated body long enough to pass through all the lifts of the heelexcept the outer or top lift, and through both outsole and insole andterminatin g in a clinching-point. The King tack, beingdestitute isubscribing wtnessesnon this 13th day of July, A. D. 1889.
